MAC 224 Brush. I know most people love the smaller 217 version for every blending job. However, I find that the fluffiness of this brush is what really creates a seamless transition of colors in the crease.

Zoeva 227 Luxe Soft Definer.Very similar to the MAC 217 but way much softer. The bristles are slightly smaller so you can achieve a more precise application that you can later blend out slowly towards the outside.

Benefit Angled Brow Brush.One of the best things about this is that it has a spoolie on the other end, which doubles up as two brushes. The bristles are strong and thin enough to mimmic the appearance of natural brow hairs.

Real Techniques Contour Brush. Aside from being a great contour tool, this brush is my favorite for many other things. I mainly like to use it to set my under eye area or just small parts of my face. Lately I've been using it to buff my cheek highlight and it leaves a very soft finish.

Zoeva 127 Luxe Sheer Cheek Brush. My favorite type of contour is with powder. I've always been a fan of angled brushes for a precise application using the tip of the angle and then blending all out with the shorter edge.

Real Techniques Blush Brush. I can't remember the last time I used another brush to apply my face powder with. I love that this one has the perfect shape to pack in product and the shorter edges to blend it all out. I've been using it to bronze my face too and the fluffiness of the brush gives me a very natural finish.
